1 Claim.

. This invention relates to improvements in winding devices and has particular reference to a machine for winding wire into coils, which coils may be dropped away from the winding machine i through gravity, thus saving considerable time in the handling of the coils.

A further object is to produce a device which is simple to manufacture.

A further object is to produce a device wherell in the end of the wire is firmly held during the Winding operation, and which will release the wire when the coil is nished and dropped from the winding machine.

ther objects and advantages will be apparent during the course of the following description. 1n the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. l is a side elevation of my device,

Fig. 2 is a top plan view of Fig. 1,

Fig. 3 is a cross sectional View taken on the line 3 3 of Fig. 2 and looking in the direction of the arrows,

25 Fig. 4 is an enlarged fragmentary detail view partly in cross section showing the wire gripping means, and

Fig. 5 is an enlarged detail view showing the manner in which the two halves of the winding wheel are locked in alignment with each other.

The usual method of winding wire requires considerable time to take the coil off from the reel or drum, after the coil has been completed. If heavy wire is being wound it often requires several attendants to handle the wire. Applicant has, therefore, devised a simple winding machine wherein when the necessary amount of wire has been wound upon a separable drum, then the two halves of the drum are drawn apart and 40 the coiled wire dropped between the two parts of the drum and rolled away, either through a chute arrangement or in any other approved manner.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a base having a head stock 6 and a-tail stock 7. These head and tail stocks may be formed in any desired manner. The tail stock 6 has bearings 8 in which a shaft 9 rotates. This 50' shaft is driven through the medium of a pulley wheel ll and has secured to its opposite end from the pulley wheel, one-half of a split drum which half is designated by the numeral 12. The 55 tail stock 7 has bearings 13 and 15, which suppoit a shaft 14, which shaft in turn carries half of the split drum, designated by the numeral 16. The half 16 and half 12 are adapted to cooperate so as to form a complete winding drum, as illustrated in Fig. 2. These drums are lined up so that a wire receiving orifice 17 is in alignment with a wire engaging clamp 18. This clamp is forced outwardly by a spring 19 and has a head 21 through the medium of which, the clamp may be pulled against the tension of the spring 19. M The shaft 14 has a handle 22 between which handie and the bearing 15, is positioned a spring 23. A collar 24 is secured to the shaft 14 and when in inoperative position, underlies a U-shaped member 26 which U-shaped member is carried upon a bell-crank lever 27 pivoted as at 28 to the tail stock 7 and connected by a spring 29 to the base 5. A handle 31 serves to rotate the bellcrank lever upon its pivot and against the tension of the spring 29. A spring 30 is secured to the bearing 13 and extends toward the hub of the disc half 16, the purpose of which spring will be later seen. Secured to the face of the drum half 12 is a stop 32 having a recess 33 and an inclined surface 34. Secured to the drum half M 16 is a pin 36, the purpose of which will be later seen.

Assuming now that the device is assembled as shown in Figs. 1 and 2 and it is desired to wind a coil, the operation will be as follows:-

If the parts are in the position shown in Fig. 1, the operator first strikes the handle 22 a blow in the direction of the arrow of Fig. 2. This causes the shaft 14 and its attached parts to move toward the left of the drawing, thus compressing the spring 23 and moving the collar 24 out from under the U-shaped member 26 to the position shown in Fig. 2. The spring 29 will immediately function to cause the U-shaped member to engage the shaft and to ride thereon at a point back of the collar 24, thus preventing the spring 23 from returning the parts from the position of Fig. 2 to that of Fig. 1. We will now assume that as this operation is taking place, the pulley 11 through any desired medium, had been delivering power to the shaft 9 and as a consequence the drum half 12 will have been rotated, as for instance, in a clock-wise direction viewed from its face and consequently the cam surface 34 of the stop will have engaged the pin 36 of the approaching drum half 16 with the result that the pin 36 will ride up the `cam 34 and drop into the recess 33, at which time the two drum halves will be together and will be rotated in unison.

Assuming that this has occurred, the operator now stops the machine, grasps the handle 21 110 stl los

pulling the clamp 18 backward towards the tension of the spring 19, inserts the wire as shown in Fig. 4 and then again applies power to the pulley. The Wire will noW be wound upon the pulley until a desired amount has been reeled into a coil. If desired, tie Wires may Ibe inserted through slots such as shown at A, which will hold the coil during transportation. Assuming now that the coil has been tied, the operator presses upon the handle 31 of the bell-crank lever 28 thus moving the U-shaped member from its position in the reel of the collar 24. The spring 23 will immediately function to draw the drum portion 16 away from the drum portion 12, at which time the hub of the drum portion 16 will engage the spring 30 and thus take up the shock or jar which would otherwise be transmitted to the bearing 13. The coil now released from the two drum halves will drop to the base 5 or onto a trough or chute from which place it will be transmitted to any desired point.

It is to be understood that the formrof my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:-

In a device of the character described, a base, a head stock, a tail stock, bearings carried thereby, a shaft carried by said head stock, a drum half carried by said shaft, means for rotating said shaft, a shaft carried by said tail stock, a drum half carried by said last mentioned shaft, means for moving said last mentioned drum half into engagement with said rst mentioned drum half, locking means for holding said drum halves in contact one with the other, said means ino1uding a collar secured to said last mentioned shaft, and a U-shaped member engaging said shaft and normally abutting one end of said collar when said drum halves are in engagement one with the other.
